Pneumatic Piston Industrial Ball Valves , Soft Seated Shut Off Anti Static Ball Valve

ZSHO Series of \"O\" Shut-off Ball Valve have two-pieces type ball structure, which includes main and auxiliary two parts body, with advantages of resistant wear valve seat, high seal tightness, excellent shutting off function and long service life performance.

 With high rated flow coefficient and small flow resistance of full bore ball core structure, Soft sealing valve seat sealing material is made by carbon fiber reinforced polytetrafluoroethylene; And hard sealing ball core and sealing ring surface has strong wear resistance by spraying tungsten carbide treatment. Valve seat is limit structure design, to maintain the torque stability; Down to up stem mounted way to prevent it from flying out; Valve seat sealing ring with antistatic design and fire retardant performance.

FEATURE:

The seats compensate automatically for wear and fluctuations of pressure and temperature. Blowout-proof stem. The stem is made separately from the ball. The lower end of the stem is designed with an integral collar to be blowout-proof, assuring sealing at all pressure. Long cycle lige. Low, uniform torques. Anti-static device. A spring-loaded pin assures the electrical continuity between the ball, stem and body, to avoid sparking during the turning of the stem to open and close the valve.

Meets ASME B16.5, B16.10 and B16.34, API 608, API 598, API 607/ ISO 10497
